Description

Product Overview

This meticulously engineered Fixture Base Plate belongs to our full range of CNC Plate series, a critical structural component designed for high-rigidity automation systems. Manufactured from premium-grade stainless steel and processed via advanced 5-axis CNC milling, this base plate features precision-machined locating blocks and straight guide slots. It serves as the primary mounting foundation for linear motion modules, testing fixtures, and robotic end-effectors in cleanroom and industrial environments. Unlike standard off-the-shelf mounting plates, this custom-machined component guarantees micron-level flatness and perpendicularity, ensuring absolute stability during high-speed repetitive operations.

Technical Specifications (CNC Machining Services Parameters)

Industry Application Scenarios

This precision base plate is primarily deployed in stringent automated environments:

• 3C Electronic Manufacturing: Used as a precise locating base for PCB testing jigs and pick-and-place robotic heads, where repetitive accuracy over millions of cycles is required.

• Semiconductor Packaging: Serves as the alignment fixture base in wire bonding and die-attach equipment. The stainless steel material minimizes particle generation (cleanroom compatible).

• Automated Assembly Lines: Acts as the main chassis for mounting pneumatic cylinders, linear guides, and sensors. The longitudinal guide slots ensure perfect alignment of sliding components.

• Automotive EV Battery Testing: Used in battery cell fixture bases that require high structural rigidity to withstand the stress of repeated compression and thermal cycling testing.

Material Analysis

The provided photo features a Stainless Steel (likely 304 or 316L) base plate. We highly recommend this material for the following reasons:

1. Corrosion Resistance: Stainless steel resists oxidation and chemical corrosion, making it ideal for humid factory environments or cleanroom applications where rust cannot be tolerated.

2. Thermal Stability: Compared to aluminum, stainless steel has a lower thermal expansion coefficient. This means the dimension of the locating blocks will not warp significantly even if the machine runs hot for hours.

3. Wear Resistance: The mating parts (like the sliding rails) frequently scratch the guide slots. Stainless steel’s hardness reduces wear and tear, extending the lifespan of the fixture.

4. Surface Passivation: The natural chromium oxide layer can be enhanced via passivation, creating a smooth, non-reactive, and easy-to-clean surface.

Tolerance and Engineering Capability

To ensure this Fixture Base Plate works seamlessly with the rail system, we apply strict control over critical dimensions:

• Straightness and Parallelism: The central guide slot must be perfectly straight. We utilize CMM inspection to guarantee that the upper surface flatness and the guide slot straightness remain within ±0.01mm.

• Locating Block Angularity: The chamfered locating blocks must act as exact V-guides. We control the angle tolerance to ±0.5 degrees to ensure there is zero rocking motion when the moving parts slide.

• Hole-to-Slot Positional Accuracy: The mounting holes must align perfectly with the mating linear rail. Our CNC machining centers ensure ±0.02mm hole positioning, ensuring a hassle-free bolt-up process.

Frequently Asked Questions (FAQ)

Q1: Do you provide free samples or prototypes for this fixture base plate?
A: We offer rapid prototyping. We charge a nominal mold/setup fee for the first piece, which is fully refundable upon mass production orders. Lead time for a single prototype is 5-7 days.

Q2: Can I change the drawing to use 6061 Aluminum instead of Stainless Steel?
A: Absolutely. We can machine this part in Aluminum, Brass, POM (Delrin), or even Titanium. Please specify your material requirements in the RFQ, and we will adjust the processing parameters and cost accordingly.

Q3: How do you guarantee the ±0.01mm tolerance on the guide slot?
A: We use a multi-step inspection process. We first check the slot using a high-precision digital height gauge, then we verify it using a coordinate measuring machine (CMM). An official inspection report (FAI – First Article Inspection) is included with every shipment.

Q4: What is your standard packaging to prevent scratches and rust?
A: Standard packaging includes:

• Oil wash and anti-rust coating.

• Individual wrapping in protective foam or VCI paper.

• Customized wooden crates or heavy-duty corrugated boxes for bulk orders, designed to withstand international logistics.
